What 91200 covers
This test uses mechanically generated shear waves, commonly vibration-controlled transient elastography, to measure liver stiffness without producing diagnostic images. It is used in evaluating conditions such as chronic viral hepatitis and fatty liver disease, where stiffness can help assess the likelihood or degree of hepatic fibrosis. Trained staff typically acquire the measurements in an outpatient setting, with a physician interpreting the results and documenting a report.
Select 91200 for the mechanically induced liver elastography service, rather than ultrasound elastography performed with imaging. The record should support the clinical reason for testing and include the interpreted results. The global service includes both the technical work, such as equipment and staff, and the professional interpretation and report. When those components are billed separately, report modifier 26 for the professional component or modifier TC for the technical component.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

91200 billing questions
How is 91200 different from ultrasound elastography codes?
91200 describes mechanically induced shear-wave testing of the liver without imaging. Ultrasound elastography codes describe elastography performed with ultrasound imaging.
Can the professional and technical portions be billed separately?
Yes. Use modifier 26 for the interpretation and report, and modifier TC for equipment and staff. Without a modifier, 91200 represents the global service.
What documentation supports reporting 91200?
Document the clinical reason for evaluating liver stiffness, the test results, and the physician’s interpretation and report.
Is the test a liver biopsy?
No. It measures liver stiffness noninvasively and does not obtain tissue for histologic examination.
What clinical situations commonly prompt this test?
It is commonly used when assessing possible fibrosis in chronic liver disease, including chronic viral hepatitis or fatty liver disease.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
